The Index of Coincidence for English language is approximatelya)0.068b...
Yes actually you said option C is correct it is actually correct but the actual answer is different
actual answer for index of coincide of English language is 0.0 667
index of coincide is a technique to find the probability of the repeating letters in an encrypted text
the index of coincide value is calculated on the basis of the probability of occurrence of a specified letter and the probability of comparing it to the same letter from the second text
so this is my answer for index of coincide of English language is 0.0667 but you have given that C is correct option

Index of Coincidence for English Language
The index of coincidence is a measure of how closely a frequency distribution of letters in a language matches the distribution of letters in a typical sample of that language. It is used in cryptography to analyze the frequency of letters in a message and determine the likelihood of a specific encryption method being used.
Calculation
To calculate the index of coincidence, you need to count the frequency of each letter in the message and then calculate the sum of squares of each frequency. Then, you divide the sum of squares by the total number of letters in the message, and finally, you multiply the result by the reciprocal of the message length minus one.
Formula
IC = Σ(fi(fi-1)) / N(N-1)
where,
IC = Index of Coincidence
fi = frequency of the i-th letter
N = total number of letters in the message
English Language
The index of coincidence for the English language is approximately 0.065. This means that the frequency distribution of letters in the English language is fairly uniform, with no significant deviations from the average frequency of letters.
Explanation
The English language has a relatively high index of coincidence compared to other languages because it has a large alphabet and a well-distributed frequency of letters. This makes it difficult for cryptographers to break codes and ciphers using simple frequency analysis.
Conclusion
In conclusion, the index of coincidence is an important tool for analyzing the frequency distribution of letters in a language and determining the likelihood of a specific encryption method being used. The index of coincidence for the English language is approximately 0.065, which indicates a fairly uniform frequency distribution.
